A process for preparing silica microparticles |
摘要 |
<p>Silica core - shell microparticles are prepared by growing a porous silica shell from a silica precursor onto the surface of non- porous silica particle dispersed in a mixed surfactant solution under basic pH conditions. The particles are hydrothermally treating in an oil-in-water emulsion system and the particles are calcined to remove residual surfactants. Optionally, the particles o may be base etched to expand the size of the pores in the silica shell. Core-shell silica particle with an ordered mesoporous layer are produced.</p> |
